The first step in slag processing is size reduction to liberate metallic iron and iron-bearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in thegrinding millwithout any balls. The latter process yields higher quality product as the iron product discharged fromgrinding millcontains as high as 80% Fe (Shen and Forssberg, 2003).
